Regional dynamic traffic assignment framework for multi-reservoir MFD models
Résumé
We investigated the ideas of an aggregated traffic modeling , as initially introduced by Godfrey (1969) and later revisited by Daganzo (2007) and Geroliminis & Daganzo (2008). For this type of modeling, the city is divided into reservoirs (Fig. 1) where the traffic conditions are approximately homogeneous and are given by a well-defined low scatter Macroscopic Fundamental Diagram (MFD). The MFD is a relationship between the aggregated flow q and aggregated density k. The traffic dynamic inside a reservoir is governed by the evolution of the vehicles accumulation n at a given time instant t Daganzo (2007).
